"Spongebob Squarepants" cheeks is not a Socionics trait. It plays no part in VI. You're just comparing one person to another.
Johnny Depp doesn't have SS cheeks and teeth-bearing smile or light eyes.
Anyway, I have a coworker who looks like SS and I think he's an ESFJ. Russ Hudson looks like him as well but his (Russ') smile is a bit more contained than my coworker's but nowhere near as contained as Johhny Depp's.
